I update every week and on 07.04.18 two finger scrolling on touchpad stopped working correctly: it seems like it cannot recognize two fingers consistently.
libinput 1.10.4

Can you show the output of libinput-debug-events while two finger scrolling?
Have you tried finding which package is the culprit by downgrading relevant packages until it is working again?

Sorry, I've been extremely busy for a couple of days. No, I haven't tried to trace it down to a specific package - I looked at the update logs and found nothing familiar which would look like its name is connected with input. Though I've tried downgrading libinput itself - it didn't fix the problem.
Output of libinput-debug-events:

Expected device added events on startup but got none. Maybe you don't have the right permissions?Upd:
Fixed permission denied errors by adding myself to input group. I'll try to capture the right moment

Judging by libinput-debug-events, it is not a libinput problem. Libinput registers two finger actions correctly
